MainActivity代码:

public class MainActivity extends AppCompatActivity {    ListView listView;    List<Bean> list = new ArrayList<>();    String[] imageUrls = {"http://img.my.csdn.net/uploads/201309/01/1378037235_3453.jpg",            "http://img.my.csdn.net/uploads/201309/01/1378037235_7476.jpg",            "http://img.my.csdn.net/uploads/201309/01/1378037235_9280.jpg",            "http://img.my.csdn.net/uploads/201309/01/1378037234_3539.jpg",};    String[] namee={"徐良","许嵩","汪苏泷","小贱"};    String[] agee={"21","43","54","65"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        listView= (ListView) findViewById(R.id.listview);        for (int i = 0; i < 4; i++) {            Bean bean = new Bean();            bean.setName(namee[i]);            bean.setAge(agee[i]);            bean.setImg(imageUrls[i]);            list.add(bean);        }        MyAdapter adapter = new MyAdapter(MainActivity.this,list);        listView.setAdapter(adapter);        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {                Intent intent = new Intent(MainActivity.this,TwoActivity.class);                intent.putExtra("name",list.get(i).getName());                intent.putExtra("age",list.get(i).getAge());                intent.putExtra("image",list.get(i).getImg());                startActivity(intent);            }        });    }}TwoActivity代码：
public class TwoActivity extends AppCompatActivity {    private ImageView imageView;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_two);        imageView= (ImageView) findViewById(R.id.imageView);        String st = getIntent().getStringExtra("image");        Glide.with(this).load(st).into(imageView);    }}

MyAdapter代码：
public class MyAdapter extends BaseAdapter {    Context context;    List<Bean> list;    public MyAdapter(Context context, List<Bean> list) {        this.context = context;        this.list = list;    }    @Override    public int getCount() {        return list.size();    }    @Override    public Object getItem(int i) {        return list.get(i);    }    @Override    public long getItemId(int i) {        return i;    }    @Override    public View getView(int i, View view, ViewGroup viewGroup) {        ViewHolder holder;        if (view==null){            holder=new ViewHolder();            view=LayoutInflater.from(context).inflate(R.layout.item,null);            holder.names=view.findViewById(R.id.tv_1);            holder.ages=view.findViewById(R.id.tv_2);            holder.images=view.findViewById(R.id.img_2);            view.setTag(holder);        }else {            holder= (ViewHolder) view.getTag();        }        holder.names.setText(list.get(i).getName());        holder.ages.setText(list.get(i).getAge());        Glide.with(context).load(list.get(i).getImg()).into(holder.images);        return view;    }    class ViewHolder{        TextView names,ages;        ImageView images;    }}

Bean类代码:

public class Bean {    String name;    String age;    String img;    public Bean(){    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getAge() {        return age;    }    public void setAge(String age) {        this.age = age;    }    public String getImg() {        return img;    }    public void setImg(String img) {        this.img = img;    }}
